OC'ing QX9650

[Toxcity]

Super Prime is a program that stresses the CPU to 100%(Dual Core). IF it isn't stable it will crash/BSOD and so on.

Can be found here.

Run two to get to 100% CPU usage,

well ive got wprime v1.62 but couldnt run 2 but it worked 4 threads at a time and i ran the 1024 and got a time of 372.5 secs...

and just ran 32 and got 11.797 secs...

That any good?

Yes 11.797 is very good.... What speed you got that running at now and what voltage?

Tox man, where you been hiding... Just use Prime 95. It will have all four cores crunching away with just the one instance of the program running.

We were overclocking one of these to 4Ghz recently. We struggled to get it stable at first (400 x10) until we realised it was one of the worst Extreme chips we had seen in a long time - needed alot of voltage! We changed it for another in the end to keep the temps down (even on a w/c system).

Hopefully you have a good chip, do you know what your chips VID is (its native automatic voltage)?

I`m pretty sure my first increase in volts is beween 3.8 & 4, probably more towards 4. VID is 1.2xx something. I know 4.2 took another step-up in volts again.

i managed so far to get to 11 x 350 but going over that and bsod boo hoo but my 3d mark gone up by 1097 to 18211 hehehe

Good to know the GX2 aint as fast as 8800GTX SLI

I have virtually the same spec as you but 8800GTXs and im getting about 19600 so far in 3dmark and that was either running the QX at 3.4 or 3.6 cant remember now.

Does depend on what system you are running.

i dont know if im allowed to pt links in a post like this but in answer to emexrulsier's comment about the 9800gx2 and his cards in sli if he looks at this page (in specific) at the 3dmark '06 scores i think he might be suprised as to how triple sli only just gets higher scores never mind dual cards in sli

http://www.overclock3d.net/reviews.php?/gpu_displays/asus_9800_gx2_1gb_en9800gx2/4

and at the highest res the gx2 overtakes the tri-sli rig so im not sure if his comment is valid or not

plus this is not on as good chip and stuff

any comments that can help me on this???

just another noob question from me. sorry. i noticed that when i up my fsb that has a direct relation to my ram speed. Does having faster ram enable you to clock your processor higher opr am i completely mistaken???

ie im on ddr2@667 at the moment, if i upgrade to ddr3 would that make it possible to clock higher than im getting at the minute.

im only getting to 11x335fsb before it bsod on me. i had it at 10x350fsb as well but higher and bsod. could this be due to the ram speed???

thanks for the help

 

[Bungral]

It could definitely be the ram limiting you.. Especially being value ram and being 4 x 1gb sticks will also make life more difficult. Even some higher speed DDR2 wouldn't go a miss and wouldn't break the bank either.

 

[Emexrulsier]

Yeah suppose if its a decent configured machine it does own the 8800GTX SLI. MY bro read this thread and said his test machine OC Q9450, DDR3 RAM, 1 GX2 scored 22k 3d mark 06

You'll have some options to adjust the divider between the RAM speed and the FSB in the BIOS on the P35 chipset, though with slower memory and higher FSB your options begin to become less and less since the RAM won't run at the higher speeds. As you raise the FSB you will see the available ram speed options change accordingly (get higher).

As bungral suggests, its certainly worth considering upgrading the RAM to faster 1066mhz speed, if you have the money for it. A 2GB kit of Corsair Dominator is very reasonable these days.

Hope that makes sense for you?

tbh you wont really notice much of a difference (if any at all) with the faster ram. Fair enough if the price is good then may aswell buy it but it wont do anything for you. Ive seen many machines with 667 ram out perform much higher speed ram. What you want to work on is the ram timings this is where it all counts with ram.

The 1066Mhez remember is DDR so its effectively 533Mhz and I doubt you will be taking your processor to over 2000Mhz QDR?

You mentioned that you were running 11 x 350 was the memory linked or unlinked? You say any higher and it would crash, which might suggests it was linked causing the ram to also be overclocked which it just might not be able to handle (if poor cooling/ambient temps).

Try unlinking the ram and see if you can push the FSB higher. Or you could also try lower the FSB and increase the multiplier. Remember increasing the FSB doesnt just affect the processor all things like NB/SB etc get effected and without proper cooling and possible voltage changes instability may occur.

A lot of motherboards don't let you totally unlink like they used to.. My 650i would let me have totally independant control over ram and cpu but now my Maximus is always linked to some extent. As for uping the multi further... From what I've read, people haven't had very good overclocks with the multi any higher than 11. Setting it to 12 made it unstable. Another thing that could be of benefit with better ram would be obviously the higher frequency, but also being able to get a nice set of timings. Value ram may not let the timings be tightened too much. Each set is different so maybe they do but I wouldn't bet on it.

Also... Having faster ram does make a difference.. I've noticed how much snappier my system is just by going from 800mhz to 1150mhz.

Surely it wouldnt run any faster. You PC would only run as fast as the slowest link. You mentioned in your sig your processor is running at 403mhz FSB your memory is set to 575Mhz, it maybe set to run faster but it all fairness it aint gunna move faster then 403. You would probably notice an even better increase if you could;

1. Run your processor at 575Mhz (2300 QDR which aint gunna happen)

2. Set your memory to run at 403Mhz (806 DDR)

How on earth would my system feel faster if it slowed my ram down 350MHz effective?? There is nothing wrong with my 4:3 divider .

The settings I'm using at the moment is pretty much as good as I can run it. It took hours of tweaking to find the right medium between CPU overclock and RAM frequency.

Anyway, back to the question in hand.. He is looking to get the most out of his beast CPU and if you talk about what RAM to pair with the QX9650... You aint talking about 667MHz value RAM.... Better RAM would enable him to obtain a higher FSB and keep a 1:1 ratio. That CPU has a hell of a lot more than 3.** GHz to give.

That said.. It might not just be the RAM.. I know that a previous dual RAM type motherboard wasn't very good at overclocking at all.. Not saying this is the case here, but it's something to think about. Again though that CPU should storm past 3.5GHz on pretty much any new board. Especially a P35.

Well if the machine is held back by its slowest component and if 10666 ddr = 533mhz and if fsb and ram is linked then my 667 ddr = 335mhz and 335 is a lot less than 533 and being theres a 200 mhz difference between the 2 surely that would mean a massive increase in the amount of difference between the fsb i can have currently and the higher one i would be able to have on the faster ram therefore enabling me to not have to rely on the multiplier so much and be able to work more with the fsb to by far increase my speed???

please let me know if by what im saying that im starting to get a grip with what you guys are on about or if im a complete git :wavey:

ps what this divider ive heard you talking about. ive heard people talking about 1:1 is that the best you can work towards???

plus talking about the board the highest multi i can have is 16x and the highest fsb is about 520 i think. i was messing with the bios yesterday and was wondering what i could get upto and the speed of the cpu went above 10GHz, obviously i didnt set it to that lmao, but it was just an inquiry into what the machine would say speed wise if i put it to max

Yes that does make a certain amount of sense. It gives you more options.. I mean to get my machine stable I've actually had to underclock my RAM slightly.. That said it's still at 1120MHz or something.

oh and ive updated my bench stats now and am getting quicker drooooool

By the way.. Faster RAM would make a big difference to your SuperPi and Prime results.
